Lukas Mertelik spent three weekends in minus 30 degree weather constructing the snowman for his two children, aged five and three.
"They love it, they crawl all over him," Mertelik told Chris Walker on the CBC Radio program Daybreak South.
He said it all started when he was shovelling snow and realized if he allowed the snow to harden in the cold weather, he could create a really unique snowman.
"Once you pack it in, it hardens really well," said Mertelik, who used steel rods and plywood to sculpt the pile higher after the snow hardened on the base.
